| 摘要 |
The invention relates to a resonator for wireless resonant energy transfer system. A resonator for a wireless power transfer system comprises an inductor adapted to receive or transmit wireless power, a main capacitor electrically connected to opposite poles of the inductor, at least two capacitor circuits electrically connected to the opposite poles of the inductor, each of the capacitor circuits comprising a capacitor in series with a switch and a diode in parallel with the switch, and a controller electrically connected to each capacitor circuit. The controller is configured to switch the switches on and off to change a capacitance of the capacitor circuits to adjust an effective capacitance of the resonator. |
